Australian musicians played and recorded some of the earliest punk rock, led by the Saints who released their first single in 1976. Subgenres of punk music, such as local hardcore acts, still have a strong cult following throughout Australia.

Many of the pioneers, like the Saints, Sydney band Radio Birdman, and young Perth musician Kim Salmon, were highly influenced by proto-punk sounds from Detroit. A distinct Brisbane punk scene emerged in the 1970s. By 1977, other bands began to form in Sydney, under the influence of Radio Birdman and other local and overseas acts. During the late 1970s, former members of Radio Birdman contributed to several new bands. These bands and other Australian and overseas punk acts were supported by public radio stations. In Melbourne scene, art rock had segued into punk, then evolved into post-punk, typified by the careers of Nick Cave, Rowland S. Howard and the Little Band scene. Another pioneering figure of Australian postpunk was Saints founder Ed Kuepper.

Music radio is a radio format in which music is the main broadcast content. After television replaced old time radio's dramatic content, music formats became dominant in many countries. Radio drama and comedy continue, often on public radio.

Music drives radio technology, including wide-band FM, modern digital radio systems such as Digital Radio Mondiale, and even the rise of internet radio and music streaming services (such as Pandora and Spotify).

An underwriting spot, known as sponsor credit (Japanese: 提供クレジット, romanized: Teikyō kurejitto) in Japan, is an announcement made on public broadcasting outlets, especially in the United States, in exchange for funding. These spots usually mention the name of the sponsor, and can resemble traditional television advertisements in commercial broadcasting to a limited extent; however, under the terms of a public broadcaster's license from the Federal Communications Commission, such spots are prohibited from being promotional (such as making product claims, using superlatives, or being more than 30 seconds long) or making any sort of "call to action" (a phrase that refers to "any device designed to prompt an immediate response or encourage an immediate sale" such as announcing prices or providing an incentive to buy). In the U.S., these restrictions apply to any television or radio station licensed as a non-commercial educational (NCE) stations, and even for non-sponsoring companies and products. However, this is not the case in Japan, as these spots can be played on both public and private broadcasters and are typically played alongside traditional commercials and appear after a show's opening theme or after a preview of a next episode or appear during a scene of a show.

Donors who contribute funding can include corporations, small businesses, philanthropic organizations, charitable trusts, and individuals. An underwriting spot can typically include the name (and, in local underwriting spots, address) of the underwriter, possibly including a company slogan (provided the slogan does not contain a call to action) and a message of appreciation, either from the sponsor indicating its pride in the program or from the station indicating its thanks for the underwriter's sponsorship. Individual spots, more apparent on public radio, often are used to express personal appreciation for the station's programming, and often also offer family members or friend best wishes on a major life event such as a wedding, anniversary or birthday.
